If you made big money on an altcoin, whether it's a quality altcoin or a MEME speculative coin, make sure to remove it from your watchlist and blacklist it forever! Otherwise, when it drops, you'll be tempted to buy the dip, and in the end, you'll lose all the profits you made before! This is a lesson I’ve learned with real money over my 13 years in the crypto space. Hope everyone can grasp the true essence of this!
